Been there twice this year once noisy once quiet.
The R6 was not static noise tested at all but was black flagged in the third session for noise.
Static at Oulton it did 97db, at 15000 revs down the start finish straight the marshall said I was aving a larf
So that must mean there is a mike/tester on the start finish straight just where your giving it the berries
I swapped it for the standard can which got me back out but the bike wasnt as crisp but still got the track time to learn the track more for when I go back on a noisy day
